Trapcode Particular Wireframe

So I'm creating a particle emitter using Trapcode particular. I keep getting this wire frame "X" that is showing up in my render. I'm wondering if this has to do with whether or not I punched my serial number in right and this "X" shows up in the demo version. I'll look into that. In the mean time I thought I would bounce it off you guys to see if it wasn't something totally obvious that I'm missing.
